Ultrasonic-microwave synergistic extraction technique applied in extracting flavonoidsofGlycyrrhiza is better than regular method.
结论：甘草黄酮的提取可优选超声-微波协同萃取法。
2
Effective factors of extractions rate offlavonoidsofglycyrrhiza in the waste residue of glycyrrhiza were studied by orthogonal design in this paper.
应用正交设计法，考察氢氧化钠浓度、体积、提取温度、提取时间等因素对甘草黄酮提取率的影响。
